Marshmallow Root
Heather Moday, M.D., of the Moday Center for Functional and Integrative Medicine, explains that, in general, the best tea ingredients for treating a sore throat are those with demulcent properties, such as marshmallow root. "A demulcent is a mucilaginous agent that forms a soothing film over the mucous membranes of the mouth and throat, relieving irritation, pain, and inflammation," she says. "This can also help soothe a cough reflex, especially with a dry cough."
